The phrase "good teeth, good appetite" makes people pay more attention to dental health. This is a topic about "import"; however, not many people care about the issue of "export", but they don't know: "poor defecation, sickness. ".
Stool is the product of the digestion and absorption of imported food under the action of a series of digestive enzymes in the human gastrointestinal tract. It is usually yellow. Its main components are water, food residue, crude fiber, bile pigment, etc. The surface of the shaped stool is covered with a layer of mucus secreted by the intestinal glands, which acts as a lubrication and is beneficial to the excretion of stool. If the color, shape, and character of the stool change, the problem is not small. It may be related to the following diseases:
One. Biliary diseases The biliary system includes intrahepatic bile ducts and extrahepatic bile ducts. The extrahepatic bile duct is not only the connecting channel between the liver and the intestine, but also the only way for the bile secreted by hepatocytes and bile duct to enter the intestine. Stones in the extrahepatic bile ducts or tumors of the extrahepatic bile ducts (sometimes pancreatic cancer infiltrates and oppresses the extrahepatic bile ducts), which will cause obstruction of the extrahepatic bile ducts. The bile cannot enter the intestine smoothly and is forced to enter the blood. jaundice. Because the bile pigment in the bile makes the stool yellow, the bile pigment in the intestine is significantly reduced, making the yellow color of the stool pale or white.
two. Gastrointestinal diseases The gastrointestinal tract usually refers to the stomach, small intestine, and large intestine. The small intestine includes the duodenum, jejunum, and ileum; the large intestine includes the cecum, colon, and rectum. The gastrointestinal tract is a tubular structure. The gastrointestinal wall is divided into serosal layer, muscle layer, submucosal layer and mucosal layer. When the innermost mucosal layer has lesions, it causes gastroduodenal ulcers and gastrointestinal tumors. At this time, there will be blood in the stool, the stool is brown or black, and the stool becomes loose stool, mucus blood stool or pus blood stool. . When rectal cancer occurs, stools are deformed and thin, accompanied by frequent stools, anal swelling, or incomplete stools. This is a symptom caused by ulceration and infection on the surface of the tumor; the frequency of symptoms is 80-90% , Stool frequency 60-70%, stool fineness 40%, mucus stool 35%, anal pain 20%, incomplete defecation 20%, constipation 10%.
three. Anal disease The anus refers to the site of stool discharge, that is, the anal canal on the anatomy. The upper part of the inner layer of the anal canal is transitional epithelium, and the lower part is keratinized stratified flat epithelium. The outer layer of the anal canal is the internal and external sphincter muscles surrounding the anal canal. The internal sphincter is a thickened circular muscle of the intestinal wall, which is an involuntary muscle; the external sphincter is a circular striated muscle surrounding the anal canal, which is a voluntary muscle, divided into subcutaneous, superficial and deep parts. When hemorrhoids or anal fissures occur in the anus, the stool will appear bright red or drip blood after the stool. Sometimes there will be pain when the stool is relieved.
In summary, changes in the color, shape and characteristics of stool are important manifestations of biliary tract disease, pancreatic disease, gastrointestinal disease and anal disease. People should pay great attention to it, otherwise it may lead to serious consequences. It can be described as "bad bowel movements, and the disease is like a mountain."
